UNITED STATES PATENT orrron FRANK F. MARTIN, OF BELOIT, WISCONSIN;

CEMENT-BLOCK-IVIOLDING MACHINE.

Patented March 27, 1906.

To all whom it may concern:

Be it knownthat I, FRANK F. MARTIN, a citizen of the United States,residing at Beloit, in the county of Rock and State of Wisconsin, haveinvented new and useful Improvements in Cement-Block-Molding Machines,of which the following is a specification,

My invention relates to improvements in molding-machines, especially formaking cement blocks.

It has for its object, among other things, to provide for molding ormaking a number of blocks at a single operation of the machine; toefiect the adjustment of the cores for varying the thickness of theblock; to enable the molding of any of the various forms or kinds ofbuilding-books now made, and to carry out these ends in a simple,expeditious, and effective meanner.

Said invention consists of certain structural features and thecombination and arrangement of parts substantially as hereinafter fullydisclosed and particularly pointed out.

In the accompanying drawings, Figure 1 is a side elevation of ablock-molding machine, disclosing the preferred embodiment of myinvention. Fig. 2 is an opposite side View thereof. Fig. 3 is a planview of the same. Fig. 4 is a vertical transverse section, and Fig. 5 isa vertical longitudinal section, of the machine. Fig. 6 is a fragmentaryplan view of portions of one side and one end of the base-forming memberof the mold.

In the disclosure of my invention I mount in a suitable frame or support1 upon rock shafts or rods 2, bearing therein, intergeared pairs oftoothed quadrants or sectors 3, connected at their outer ends by linksor rods 4 to the ends of cross-bars 5 secured to the under sides of thelongitudinal bars 5 of a supplemental frame or carriage 5. Said sectorsor quadrants are effective for coaction, the

-shaft of one pair thereof having secured thereto a manually-actuatedlever 3 and which lever is suitably braced in position by effectingconnection, preferably as at 3 be tween said lever and the top edge ofone of said sectors or quadrants. Said lever is suitably equipped with aspring or automatically pressed detent 3, adapted to engage aholding-rack 3 secured to the frame 1, said detent being controlled by afinger-actuated or supplemental lever 3", suitably connected to saiddetent and pivoted upon the lever 3*.

Said frame or support 5 is guided in its move= ment by and has passingthrough apertures in its end bars 5 rods 6, suitably secured in thebottom and top end bars of the main frame or support 1. Said carriage 5has suitably supported or superposed thereon a suitable height ordistance therefrom, preferably by brackets or arms 6 duplicate bars orcores 6 preferably rectangular in cross-section and of the requisitedimensions, said arms or brackets being fixed at their ends to saidcarriage and cores.

Preferably adjustably applied to the top of the main frame 1 upon itslongitudinal or lateral bars, as at 7 7 are additional bars 7. Alsosuitably applied or hinged to the top of said frame at its ends areplates 8, forming the end members of the mold. To the bars 7 aresuitably hinged or pivoted, as at 9*, additional plates ,9, each havinga plane or a configurated surface to produce, for instance, upon themolded product or block a rockface imitation, said latter plates formingthe lateral mold members. The bars 7 and plates 8, forming the base,lateral, and end portions of the mold members, are adapted to partiallyoverlie one another and have their thus opposed surfaces provided withengaging setscrews 8 and slots 8 for varying the adjustment of thelateral and end walls or members of the mold as occasion may require.

Upon the main frame 1 is placed the blockoff-bearing palate 10 or thebottom member of the mold of any suitable construction and havinglateral longitudinal openings 10 therein for the passage therethrough ofthe cores 6 said palate also having therein a central longitudinal slotor slit 10 for the re' ception of an edgewise-arranged plate orpartition 11, secured also bybrackets or arms 11 to the core-carryingframe or carriage 5.

In operation the cement or material is filled and suitably tamped in themold, presumably the cores 6 and partition 11 having been previouslyadjusted to the required altitude or position within the mold, accordingto the thickness of wall it may be desired to impart to the prospectiveblock. After the contents of the mold have received the propertreatment-been shaped and dressed off to produce the requisite blockformationsthe cores, together with the partition,

are suitably depressed or withdrawn from the mold, the resultantplurality of blocks are borne off upon the palate 10 for drying bymanually removing the latter, as will be appreciated. Of course therelative height of the partition or plate 11 and the cores 6 will besuch that the former may always be effective for the formation of twoblocks, while the latter may be varied or controlled as to theiradjustment regarding the thickness of the walls of the blocks, as willbe readily understood.

By the requisite adjustment of the side and end walls of the molds it isobvious that blocks of varying dimensions may be 'roduced. Also it isnoted that with this machine blocks of any of the various styles .orformations previously adopted may be molded thereon.

Latitude is allowed as to details herein, as they may be changed withoutdeparting from the spirit of my invention.

I claim- 1. A machine of the character described, comprising astationary upright frame-sup- ,port, end and lateral mold membersarranged thereon and constituted of base portions one partiallyoverlying the other and provided in their thus opposed surfaces withengaging slots and set bolts or screws, respectively, and of hinged orpivoted ends and sides proper connected to said base portions, andadapted for mutual retention in operative position.

2. A machine of the character described, comprising a stationary uprightframe-support end and lateral mold members arranged thereon andconstituted of base portions one partially overlying the other andprovided in their thus opposed surfaces with engaging slots and setscrews, respectively, and of hinged or pivoted ends and sides properconnected to said base portions and adapted for mutual retention inoperative position, a vertically-movable frame or carriage sliding uponthe aforesaid frame-support and bearing duplicate cores and a partitionarranged equidistantly between said cores, said cores and partitionbeing received within the chamber formed by said mold members, andactuating mechanism for said core and partition-bearing carriage.

In testimony whereof I affix my signature in presence of two subscribingwitnesses.
